### Question: What are the symptoms of Becker's muscular dystrophy?
### Response: Females rarely develop symptoms. Males will develop symptoms if they inherit the defective gene. Symptoms usually appear in boys at about age 12, but may begin later.
Muscle weakness of the lower body, including the legs and pelvis area, slowly gets worse, causing:
Difficulty walking that gets worse over time; by age 25-30 the person is usually unable to walk Frequent falls Difficulty with running, hopping, and jumping Loss of muscle mass
Muscle weakness in the arms, neck, and other areas is not as severe as in the lower body.
Other symptoms may include:
Breathing problems Cognitive problems (these do not get worse over time) Fatigue Loss of balance and coordination
